Specification of Letters Patent. Patented June 29, 1915 Application filed July 31, 1914. Serial in). 854,259.

Chatham, New Jersey, have invented new and useful Improvements in Sash-Fasteners, of whichthe following is a speclfication.

This invention relates to a window sash fastener.

One of the objects of the invention is to provide a device of this character by means of which the sashes of a window may be locked in open or closed position against relative movement.

Other objects are to provide a device of this character which is simple in construction and therefore economical to manufacture, which is efficient, which is easily manipulated and not liable to get out of order, and whichmay be readily applied to any existing window.

Other objects will in part be obvious and in part be pointed out hereinafter.

In the accompanying drawings showing an illustrative embodiment of the invention, and in which the same reference numerals refer to similar parts of the several figures, Figure 1 is an elevational view of a window showing the device in position, the upper sash being opened; Fig. 2 is a sectional view on the line 2'-2 of Fig. 3; Fig. 3 is a front view of the device.

Referring to the drawings, 1 and 2 represent the upper and lower sashes, respec tively, of a window of any ordinary construction. The improved sash fastener comprises a plate 3 to which a second plate a is hinged, as clearly shown in Fig. 2. The plate 3 is secured to the upper rail of the lower sash 2 in any suitable manner, as by screws 5 passing through holes formed in the plate 3, which holes are preferably positioned centrally of said plate for a purpose hereinafter set forth.

' Adjacent the free end of plate 4 is a hole through which a pin 6 extends, which pin is preferably rotatable about its axis. The end of the pin 6 which projects beyond the plate 4: is adapted to engage any one of a series of recesses 7 formed in the side rail of the upper sash 1. Moimted upon the other end of the pin is a locking member 8 which is adapted to rotate with the pin. The lower end of the locking member 8 is adapted to engage the upper surface of the plate 3 when the locking member is in its vertical or operative position, as clearly shown in Fig. 3, thereby preventing relative movement of the hinged plates, and when in this position the locking member will overlie the screws 5 thereby preventing them from being withdrawn by any person attempting to remove the device.

If desired a plate 9 provided with holes registering with the recesses 7 may be secured to the side rail of the upper sash in order to prevent the woodwork from being worn or damaged by the pin 6.

The operation of the device, which should be largely obvious from the description and illustration, is as follows :'Assuming the parts to be in their operative position, as shown in full lines in Figs. 2 and 3, in which the sashes are shown closed, if it is desired to open the window it is merely necessary to move the locking member 8 sidewise into the position indicated in dotted lines in Fig. 3 after which the plate at is rotated about the hinge into the position indicated in dotted lines in Fig. 2, thereby withdrawing the pin 6 from the recess 7 with which it was in engagement. Either one or both of the sashes may then be moved into any desired position after which they may be locked against further relative movement by reversing the above described operation.

When the sashes are locked in the manner indicated in Fig. 1 they cannot be moved relatively to one another, although of course they may both be moved together to leave an opening at the top of the window, or at the bottom of the window, or if desired they may be so moved that there is an openingat both the top and the bottom ofthe window.

Having described this invention in connection with an illustrative embodiment thereof, to the details of which disclosure the invention is not, of course, to be limited, what is claimed as new, and what is desired to be secured by Letters Patent is set forth in the appended claims 1. In a sash fastener, in combination, a plate adapted to be secured to one of the sashes, a second plate hinged to said first plate, a pin carried by said second plate adapted to engage a recess in the other of said sashes, and'a locking member operatively connected to said pin and being adapted' for engagement with the first plate to lock said second plate against movement relatively to said first plate when said pin occupies its recess engaging position.
